a few tidbits about the nx console in the sentra, at least for me.
The center console will get in the way of your belt buckle, so it may be a little harder to buckle your seatbelt and to press the button to take off your seatbelt. Because of the compartment on the console, it leaves little room for the belt buckle.
Also, my sentra had airbags and there was a small airbag unit of some sort on the floor in the back. My sentra center console had an extention to cover the unit while the nx console did not.
